Abstract

AIM: The purpose of the study was to compare Cardiopulmonary Exercise Test (CPET) with Left Ventricular Dysfunction (LVD)-36 questionnaire which is composed of 36 questions determining life quality of patients with chronic left ventricular systolic dysfunction. MATERIAL AND METHODS: The patients with left ventricular systolic dysfunction (ejection fraction (EF)$\leq$ %40) were included in this study. Totally 57 subjects were studied. There were 48 men and 9 women with a mean age of 62±7 years, mean ejection fraction of %34.7±4.1. Breath by breath CPET was performed to these subjects. At the same time with CPET; LVD-36 test questions which had to be answered as "true" or "false". Then we searched the correlation of the peak oxygen consumption (VO2) with the sum of the questions that were answered as "true". RESULTS: There was reverse correlation with peak VO2 (ml/min/kg) and the number of questions answered as "true". Patients in functional capacity Weber A (>20 ml/min/kg) answered 10±8 questions as "true"; 10 patients in Weber B (16-20 ml/min/kg) answered 16±10 questions as "true"; 11 patients in Weber C (10-16 ml/min/kg) answered 17±9 questions as "true"; and 6 patients in Weber D (<10 ml/min/kg) answered 31±4 questions as "true" respectively. As the functional capacity of patients decreased from A to D; number of questions that they answered as "true" increased. Correlation coefficient with VO2 and the number of questions that were answered as "true" was (r= -0.568 and p=0.0001). There was no statistical correlation with the number of questions answered as "true" and ejection fractions of the patients (r=-0.133; p=0.475). CONCLUSION: There is statistical correlation with the functional capacity and the answers to LVD-36 questionnaire in patients with left ventricular dysfunction. Our study shows that LVD-36 is a simple, useful and an easily applicable test.

Özet

AMAÇ: Kronik sol ventrikül sistolik disfonksiyonlu olguların yaşam kalitelerini 36 adet soruyla değerlendiren ²Left Ventricular Dysfunction'' (LVD)-36 anketini; Kardiyopulmoner Egzersiz Testi (KPET) ile karşılaştırmayı amaçladık. GEREÇ VE YÖNTEM: Çalışmaya sol ventrikül sistolik fonksiyon bozukluğu olan (ejeksiyon fraksiyonu (EF) $\leq$%40) 48'si erkek; 9'u kadın toplam 57 olgu alındı. Olguların yaş ortalamaları 62±7 yıl idi. Ortalama EF'leri %34.7±4.1 idi. Olgulara solunumdan solunuma KPET uygulandı. KPET ile aynı süreç içerisinde LVD-36 sorularına "doğru" ve "yanlış" olmak üzere yanıt vermeleri istendi. Daha sonra hastaların "doğru" olarak nitelendirdikleri soru adedi toplandı, pik oksijen tüketimi (VO2) ile ilişkisi araştırıldı. BULGULAR: Hastaların pik VO2 değerleri ile (ml/dak/kg), doğru olarak işaretledikleri soru sayısı arasında negatif korelasyon gözlendiği dikkat çekti. Fonksiyonel kapasitesi Weber A (>20 ml/dak/kg) olan 12 olgunun test üzerinde "doğru" dedikleri yanıt sayısı 10±8 iken, Weber B'ye (16-20 ml/dak/kg) dahil olan 13 olgunun 16±10, Weber C'ye (10-16 ml/dak/kg) dahil olan 27 olgunun cevabı 17±9, Weber D'ye (<10 ml/dak/kg) dahil olan 5 olgunun ise"doğru" olarak nitelendirdikleri soru sayısı 31±4 idi. Hastaların fonksiyonel kapasiteleri azaldıkça, testteki sorular için daha çok "doğru" seçeneğini işaretledikleri gözlendi (r=-0.568; p=0.0001). Testte işaretlenen "doğru" seçeneği sayısı ile hastaların EF'u arasında ise anlamlı korelasyon olmadığı tespit edildi (r= -0.133; p=0.475). SONUÇ: Sol ventrikül sistolik disfonksiyonlu olgulara uygulanan LVD-36 sorularıyla hastaların fonksiyonel kapasiteleri arasında anlamlı bir korelasyon gözlenmektedir. Bu çalışma LVD-36'nın kolay uygulanabilen, basit ve yararlı bir test olduğunu kanıtlamaktadır.
